450 Servo horn screw size?

[chad]

My dominator kit didn't come with the servo horn screws. I figured out the cyclic servo ones by looking in the manual, but it doesn't specify what size it is for the tail servo. the cyclic servo horn screw were M2X4mm but the tail servo is bigger

I think its M3 Chad.
The blade grip screws on your Dominator are M3. Take one of those and test it out in the servo.

huh. you're right i pulled the blade grip screw out and tested in the servo and it fits. so the next question is the lenght. it should be about the same as the other servos you would think right?

thanks alot!

Again screw in the blade grip bolt.
Measure how much goes in to the servo gear.
Add 2mm for the servo horn, that should do it
